Hi everyone,
I have a lot of info in this one and I’m hoping someone has the solution for me.
My brother has an ‘06 sport edition v6 that stopped blowing cold air a few weeks ago (blower motor runs when A/C button is pressed but only warm air). The light on the A/C button was also blinking. I replaced the magnetic clutch relay but still no cold air. Below I will list the other things Ive tried as troubleshooting:
- Bypassed the relay with jumper cables in the fuse box. This causes the magnetic clutch to engage, blow cold air, and work perfectly for as long as you have the relay bypassed. However, when the relay, which is definitely not faulty, gets plugged back in, the magnetic clutch engages for about 1-3 seconds before quitting. It does not come back on after.
- shorted the pressure switch by the high side pressure valve. This didn’t have any effect so I have to assume this switch is fine.
- used pressure gauges to test if I have Freon. The levels seem fine to me but I will post the image of the pressures below.
- read on this forum about the thermistor. Removed the glove box and shorted the thermistor wires. Still no effect.
So, when I bypass everything at the fuse box, the compressor works fine as I described above so I feel like I must be missing some sensor somewhere that may have gone bad. Anyone have any other suggestions?
